Variations in atmospheric aerosols and electrical conductivity at Roorkee during the total solar eclipse of October 1995

Continuous measurements of some meteorological and electrical parameters in conjunction with the total solar eclipse of 24 Oct. 1995 were made from 22 to 27 Oct. 1995 at Roorkee (29 degrees 52' N, 77 degrees 53'52'' E, 275 m above sea level). Roorkee observed 90-92% maximum obscurity of eclipse, as it was close to the path of totality. The event lasted from 7.10 a.m. to 9.30 a.m. (IST; 0140-0400 hrs GMT). Considerable increase of aerosols and positive and negative conductivities were recorded during the eclipse with respect to those made on any other day. Increase in relative humidity and decrease in temperature were also observed during the eclipse.
